A contact lens (200) comprising one or more microchannels (10) for transport of liquid through the lens is provided. The contact lens (200) can be made by contacting a curable composition (50) with a microfiber (80) that is insoluble in the curable composition (50); curing the curable composition (50) to provide a polymeric lens body (85) with the microfiber (80) embedded therein; and contacting the polymeric lens body (85) with a solvent to dissolve the microfiber (80) L'invention concerne une lentille de contact (200) comprenant un ou plusieurs microcanaux (10) permettant le transport de liquide à travers la lentille. La lentille de contact (200) peut être réalisée par la mise en contact d'une composition durcissable (50) avec une microfibre (80) qui est insoluble dans la composition durcissable (50); le durcissement de la composition durcissable (50) afin obtenir un corps de lentille polymère (85) dans lequel la microfibre (80) est incorporée; et la mise en contact du corps de lentille polymère (85) avec un solvant afin de dissoudre la microfibre (80).
